The dimensions of dangerousness

Law and Human Behavior - Treatment of dangerousness in both sociolegal research and clinical practice has neglected to consider the multidimensional nature of the construct. An attempt was made to...     

The dimensions of dangerousness revisited

In this article, we extend our previous study on clinical predictions of violence using the Dangerous Behavior Rating Scale by increasing follow-up interval from 2 to 6 years and supplying new data on prediction-outcome correlations for multidiscipline assessors. A total of 162 accused persons remanded for evaluations at METFORS were assessed using three criterion measures: subsequent violence, criminality, and general incidents. Statistical analyses revealed a range of predictive performance, contingent on several conditions including the identities of evaluators, categories of subjects, and length and context of follow-up. Even prognostications yielding the highest magnitude coefficients, reaching 53 in the case of psychometric forecasts of behavior in psychiatric hospitals, failed to account for more than 28% of the prediction-outcome covariance. Implications of the results are considered for the future role of the dangerousness construct.The research project described in this article was funded by the Social Sciences and Humanities Research Council of Canada, the Canadian Psychiatric Research Foundation, the Solicitor General Canada, the LaMarsh Research Program on Violence and Conflict Resolution, the Ontario Ministry of Health, Simon Fraser University, the Clarke Institute of Psychiatry, and the psychopathy project supported under the sustaining grant provided by the Solicitor General, Canada, to the Centre of Criminology, University of Toronto.

Measuring patient violence in dangerousness research

Research on the dangerousness of mental patients has paid only limited attention to the issues surrounding the measurement of violent events. This article reviews the possible methods for measuring patient violence and comments on the benefits and drawbacks associated with different strategies. It is argued that there are usable approaches beyond official records and that development of these alternatives is a necessary step for advancing theory in this area.     

The aged and the dangerousness criterion in involuntary civil commitment

Using data from official court records and observations in court hearings throughout one state with a typical reform statute, this study investigates the elderly against whom petitions are brought for involuntary civil commitment. In relation to their proportion in the population, the aged are only slightly more likely than younger persons to become respondents in commitment proceedings; but they are over three times more likely to remain involuntarily hospitalized and to be subjected to recommitment proceedings. Once brought into the process, they are more likely than younger respondents to be committed and are more likely to be successively recommitted. In analyzing court testimony, focus is on evidence of dangerousness since involuntary commitment is limited to the mentally ill who are dangerous. Almost half of the young old initial respondents with formal hearings have no testimony alleging dangerous behavior and more than half of the old old have no such testimony. The alleged dangerous acts of the aged tend to be unintentional harm rather than assault.     

Ideology and dangerousness: The case of Lisa Colleen neve

On November 17, 1994, a superior court judge in Alberta, Canada, declared that Lisa Neve was a dangerous offender (DO) and sentenced her to serve an indeterminate (life) term. A young Aboriginal prostitute, she had been in and out of psychiatric institutions and jails since a teenager; and was before the court for sentence on a robbery and assault with a weapon charge. Using a case study approach, this essay explores the issues of class conflict, racism, sexism, and sociology of psychiatric diagnosis. Her DO designation was subsequently reversed on appeal, revealing the fortuitous intersection of race, gender, and class.     

反思精神障碍强制医疗的“危险性”原则

很多国家精神卫生立法在强制医疗人院标准方面都适用了“危险性”原则,我国《精神卫生法》也在其列。然而,“危险性”原则是基于三个错误的假设,因此实际上“危险性”原则可能会增加精神疾病对患者的伤害和较大程度增加社区危险的风险。本文呼吁参考Large及Richardson的观点及美国部分州与苏格兰精神卫生立法的实证经验,在“危险性”原则基础上补充“拒绝治疗的能力”评定作为精神障碍者强制医疗入院标准。
